Revolutionary 3-D and 4-D ultrasound imagery sheds light on the delicate, dark world of a fetus as never before. Cutting-edge technology makes it possible for us to explore each trimester in amazing new detail. In In the Womb, follow a rare fetoscope operation, performed in utero with the hope of correcting life threatening complications before birth.

Join geneticist Spencer Wells and a team of technicians from National Geographic's Genographic Project as they trace the human journey through time and space, from our origins in the heart of Africa to the ends of the world. Cutting edge science, coupled with a cast of New Yorkerseach with their own unique genetic historywill help paint a picture of these amazing journeys.

From the moment of conception, every human embryo embarks on an incredible nine month journey of development. Now, cutting-edge technology makes it possible for us to open a window into the hidden world of the fetus and explore each trimester in amazing new detail. Revolutionary 3-D and 4-D ultrasound imagery sheds light on the delicate, dark world of a fetus as never before and follows a rare fetoscope operation, performed in utero with the hope of correcting life threatening complications before birth.

Over the last three decades, science has been advancing our understanding of stresshow it impacts our bodies and how our social standing can make us more or less susceptible. From baboon troops on the plains of Africa, to neuroscience labs at Stanford University, scientists are revealing just how lethal stress can be. Research tells us that the impact of stress can be found deep within us, shrinking our brains, adding fat to our bellies, even unraveling our chromosomes. Understanding how stress works can help us figure out ways to combat it and how to live a life free of the tyranny of this contemporary plague. In Stress: Portrait of a Killer, scientific discoveries in the field and in the lab prove that stress is not just a state of mind, but something measurable and dangerous.

If you haven’t heard of Plant 42, you are not alone. Go inside America’s “black world” of off-the-record projects developed in secret. Host Jake Ward, editor of Popular Science, explores the little-known projects being built in America that are so confidential, some are said not to exist. From futuristic aircraft flying faster than the speed of sound, to stealth weapons and propulsion systems, Ward works every angle he canon and off the recordto take us as deep inside the secret site as possible.
